Thalia, Guardian of Thraben, like Kitchen Finks, is a main-deck card in some decks but also comes in from sideboards to fight against spell-based combo like Storm, while also being helpful against pretty much any deck with a lot of non-creatures

Lets look at Nahiris Molten Ambition by the numbers: 36 Equipment 28 Equipment @ 3mv or less 14 Living Weapons 5 Creatures that can tutor up Equipment or put it into play (Kassandra, Gilgamesh etc) 5 Early drop Creatures that reduce or free equip (Puresteel Paladin, Fervent Champion, Helitrooper etc) 31 Creatures (+4 if you factor in Pre-War Formalwear, Raven Clan War-Axe, Emerias Call and Inkmoth Nexus) 36 Lands (+ Land Tax, Sword of the Animist, Bitterthorn, Sword of Hearth and Home, & 2* Equipment Tutors) So, with 36 Equipment and 5 creatures that can find one, were at a whopping 96.9% to see two of them by Turn 3
